Definitions
- the invention relates to a reactor for the anaerobic purification of wastewater, in particular of waste water from the paper industry, comprising a reactor vessel, a plurality arranged in the lower region of the reactor vessel feeds for supplying wastewater to be cleaned in the reactor, at least one drain for discharging purified water and at least a sediment discharge, wherein one or more feeds are fed by a supply line and multiple supply lines from a collecting supply line.
- the invention also relates to a process for the anaerobic purification of wastewater, in particular of waste water from the paper industry with a reactor comprising a reactor vessel, a plurality of feeds arranged in the lower region of the reactor vessel for supplying wastewater to be purified into the reactor, at least one effluent for discharging purified liquor Water and at least one sediment, wherein one or more feeds are fed by a supply line and a plurality of feed lines from a collecting feed line.
- wastewater treatment For wastewater treatment, a variety of mechanical, chemical and biological processes and corresponding reactors are known.
- biological wastewater treatment the wastewater to be treated with aerobic or anaerobic microorganisms is contacted, which contains the organic impurities contained in the wastewater in the case of aerobic microorganisms predominantly to carbon dioxide, biomass and water and in the case of anaerobic microorganisms mainly to carbon dioxide and methane and only reduce a small part to biomass.
- the biological wastewater treatment process in recent time increasingly carried out with anaerobic microorganisms, because in the anaerobic wastewater treatment must not be introduced under high energy consumption oxygen in the bioreactor, in the purification of high-energy biogas is generated which can subsequently be used for energy production, and significantly lower amounts of excess sludge are generated.
- the reactors for anaerobic wastewater treatment are subdivided into contact sludge reactors, UASB reactors, EGSB reactors, fixed bed reactors and fluidized bed reactors.
- the microorganisms in fixed bed reactors adhering to stationary support materials and the microorganisms in fluidized bed reactors on freely movable, small carrier material are used in the UASB and EGSB reactors in the form of so-called pellets.
- UASB upflow anaerobic sludge blanket
- EGSB expanded granular sludge bed
- the wastewater or a mixture of wastewater to be purified and already purified wastewater from the outlet of the anaerobic reactor is fed to the reactor via an inlet in the lower reactor region and passed through a sludge bed containing microorganism pellets located above the feed.
- the microorganisms form in particular methane and carbon dioxide-containing gas (which is also referred to as biogas), which partially accumulates in the form of small bubbles on the microorganism pellets and partly rises in the form of free gas bubbles in the reactor upwards. Due to the accumulated gas bubbles, the specific gravity of the pellets decreases, causing the pellets to rise in the reactor.
- separators are usually arranged in the middle and / or upper part of the reactor in the form of gas hoods, under whose ridge biogas accumulates, which forms a gas cushion.
- Purified water freed of gas and microorganism pellets rises in the reactor and is withdrawn via overflows at the top of the reactor.
- Such processes and corresponding reactors are described, for example, in EP 0 170 332 A and in EP 1 071 636 B. Particularly important in the processes described above is the uniform distribution of the wastewater fed to the reactor via the feed over the reactor cross-section in order to achieve good mixing of the sludge pellets in the reactor, the water in the reactor and the wastewater added. In order to meet these requirements, a number of reactors equipped with corresponding feed distributors have already been proposed.
- the object of the invention is to ensure the most uniform possible supply of wastewater to be cleaned at the bottom of the reactor vessel.
- pellets in particular are understood to mean granulated biosludge.
- this object is achieved in that at least the majority of the feed lines of a collecting feed line supplies a maximum of 10 feeds with wastewater to be cleaned and at least the majority of these feed lines each have a control valve. - A -
- the distribution of the supply of wastewater to be cleaned can be better controlled over the cross-section of the reactor vessel and thus evened out. This is still possible if individual inlets of sediment deposits are partially or completely covered.
- Reactor so that the feeds can be passed through the bottom or side into the reactor vessel. It is also advantageous if at least the majority of the feed lines, preferably all feed lines are led out of the reactor vessel. Since most of the feed distributor is outside the reactor vessel, this is both easy to implement, but on the other hand, the accessibility to measuring and control devices, provided that they are installed or mounted in this located outside of the reactor vessel part of the supply line.
- At least the majority of the feed lines preferably all feed lines should have a flow measuring device, so that it is relatively easy to determine whether and how many feeds of the corresponding feed line are closed. On this basis, the feed distribution over the cross section of the reactor can be better controlled.
- At least one inlet preferably all inlets of at least one inlet line, are aligned to form a sediment discharge.
- the feeds should also preferably be distributed uniformly over the bottom of the reactor vessel in the interests of a uniform distribution of the feed quantity of wastewater.
- the reactor vessel has at least one downwardly tapering funnel and the sediment discharge is at the lower end of the funnel.
- the reactor as well as the funnel can have a round or angular cross-section.
- the funnel-shaped reactor bottom in particular in the form of a downwardly tapering single cone or double cone, ensures that solids falling from the upper reactor part with a high specific weight fall as far as the top of the funnel and can be removed therefrom. As a result, an accumulation of sediments in the area of the feeds, which leads to the formation of dead spaces and to a reduction of the effective reactor cross section, can be avoided.
- the reactor bottom can also be formed by several funnels with sediment discharge.
- At least one central supply line for supplying liquid should open into the lower end of the funnel, wherein the supplied liquid can be formed by wastewater to be purified, treated wastewater or a mixture thereof. This liquid can be used to reactivate the pellets and / or to support sediment separation and removal.
- a plurality of supply lines each have a control valve and at least individual control valves are at least temporarily opened at different intervals.
- the flow rate in the supply lines is adapted to the requirements and, if necessary, also reduced to zero.
- the flow rate should be measured and the control valves controlled in dependence on the flow rate in the feed lines, at least for some, preferably all feed lines.
- Figure 1 a schematic longitudinal section through a reactor
- FIGS 2 and 3 various Zulaufverteilsysteme at the bottom 8 of the reactor.
- the bioreactor shown in Figure 1 comprises a reactor vessel 1, which is cylindrical in its middle and upper part and tapers in its lower part downwardly conically.
- the Zulaufverteilsystem In the lower part of the reactor, i. in the funnel the Zulaufverteilsystem is accommodated for the supply of the waste water to be cleaned.
- each of the separator 11, 12 consists of several layers of gas hoods 13; in the present Fig. 1, however, only one layer gas hoods 13 is shown for reasons of simplicity per each separator 11, 12.
- Above the upper separator 12 are processes 4 each in the form of an overflow, over which the purified water is withdrawn from the reactor.
- a gas separation device 14 is arranged, which is connected to the two separators 11, 12 via the lines 15.
- a sinking line 16 leads from the bottom of the gas separation device 14 into the lower part of the reactor vessel 1.
- a sediment 3 and a central supply line 10, 3 solids or a suspension of solid and liquid can be withdrawn from the reactor vessel 1 via the sediment trigger and via the central supply line 10 liquid for rinsing the lower reactor vessel part 1 can be introduced.
- the Zulaufverteilsystem is formed by a plurality of inlets 2, which are arranged evenly at the bottom 8 of the reactor vessel 1, here the inner wall of the funnel.
- the wastewater to be purified is fed into the reactor vessel 1. Only a few, specifically here not more than five feeds 2 are supplied by a common feed line 5 with the wastewater. Each feed line 5 is connected via a respective control valve 7 with a plurality of feed lines 5 associated collecting feed line 6.
- the feeds 2 belonging to a feed line 5 can be arranged next to and / or above one another in the reactor vessel 1.
- wastewater to be purified is introduced into the reactor vessel 1 via the feeds 2, an intimate mixing between the wastewater fed in and the medium in the reactor coming from already partially purified wastewater, microorganism pellets (in FIG indicated by small dots) and small gas bubbles.
- the introduced waste water flows slowly from the feeds 2 in the reactor vessel 1 upwards until it enters the fermentation zone containing microorganism-containing sludge pellets.
- the microorganisms contained in the pellets mainly decompose the organic impurities contained in the waste water into methane and carbon dioxide gas.
- the generated gases produce gas bubbles, the larger of which detach from the pellets and bubble in the form of gas bubbles through the medium, whereas small gas bubbles adhere to the sludge pellets.
- the free gas bubbles catch in the gas hoods 13 and form under the ridge of the gas hoods 13 a gas cushion.
- the gas collected in the gas hoods 13 and a small amount of entrained pellets and water are removed, for example via an existing in the end face of the gas hoods 13, not shown opening from the gas hoods 13 and passed through line 15 into the gas separation device 14.
- the water, the rising microorganism pellets, and the gas bubbles not already separated in the lower separator 11 continue to rise in the reactor vessel 1 up to the upper separator 12. Due to the decrease of the hydrostatic pressure between the lower separator 11 and the upper one Separator 12 detach the last small gas bubbles from the microorganism pellets that have passed into the upper separator 12, so that the specific gravity of the pellets increases again and the pellets sink downwards.
- the remaining gas bubbles are collected in the gas hoods 13 of the upper separator 12 and in turn transferred to the end faces of the individual gas hoods 13 in a gas manifold, from which the gas is passed via the line 15 into the gas separation device 14.
- the now purified water rises from the upper separator 12 further upwards until it is withdrawn via the overflows from the reactor vessel 1 and discharged through a drain line.
- the gas separation device 14 the gas separates from the remaining water and the microorganism pellets, wherein the suspension of pellets and the wastewater is recirculated via the sink line 16 into the reactor vessel 1.
- the outlet opening of the sinking line 8 opens into the lower part of the reactor vessel 1, where the recycled suspension of pellets and waste water is mixed with the reactor 1 via the inlets 2 supplied wastewater, after which the cycle begins again.
- wastewater wastewater contains more or less solids.
- Wastewater from the paper industry contains significant concentrations of solid fillers and lime. After the solids-containing wastewater has left the feeds 2, it rises up into the cylindrical reactor vessel part. The proportion of solids contained in the waste water, which exceeds a minimum of specific gravity, decreases already after leaving the inlets 2 in the down-tapering funnel and collects there.
- part of the calcium dissolved in the waste water precipitates on the slurry pellets after the waste water has risen to the mud bed zone.
- some of the sludge pellets exceed a critical specific gravity and as a result sink from the sludge bed and also accumulate in the hopper.
- the inlets 2 are designed and aligned with the sediment 3, that the sinking from top to bottom pellets do not deposit on the inlets 2, but slip off the outer surface of the inlets 2 and also accumulate in the top of the funnel.
- the sediment collecting at the top of the reactor vessel 1 sediment can be withdrawn continuously or batchwise from the reactor as needed.
- liquid into the lower part 2 of the reactor vessel via the central supply line 10 can be waste water to be purified, recirculated wastewater from the reactor, fresh water or a mixture thereof.
- the reactor shown in Figure 2 in contrast, has a quadrangular cross-section. As can be seen from the top view of the bottom 8 of the reactor, a plurality of feed lines 5 are guided here laterally from the reactor wall into the reactor vessel 1.
- Each of the feed lines 5 has a maximum of five inlets 2, which are directed here in the upper part of the reactor vessel 1. This is to support the mixing of the fed via the feeds 2 wastewater with the medium in the reactor vessel 1.
- each inlet line 5 associated flow measuring device 9 and a control valve 7 for influencing the flow rate in the supply line. 5
- control and measuring devices 7,9 outside of the reactor vessel 1 is not as susceptible to interference as inside the reactor in the partly aggressive atmosphere. This also simplifies assembly and repair.
- the flow measuring devices 9 can be easily determined whether single or multiple feeds 2 a feed line 5 are impaired. In the event of a blockage, attempts can then be made, for example by a brief increase in pressure in the respective supply line 5, to flush the clogged inlets 2 again. The pressure increase can also be done by closing other supply lines 5.
- the pressure in the feed line 5 can be increased if it is assumed that all inlets 2 of this feed line 5 are impaired.
- each supply line 5 has here only one inlet 2, which is arranged so high above the floor 8, that it has a possible
- the feed lines 5 can also be designed so that they are preferably adjustable from outside the reactor. In this way, the height and orientation of the inlets 2 of the corresponding supply line 5 can be changed or adapted relatively easily.
- the bottom 8 is designed generally inclined, wherein the inclination is realized so that the sediment slides in the direction of a sediment 3 at the bottom 8 of the reactor.
- all inlets 2 are aligned with this sediment 3.
